<p>Zigbee最大的问题是产品之间不兼容。不过Zigbee主要瞄准工业环境监控市场，一般不会有从多家公司采购的情形，所以兼容问题也就罢了。在消费电子方面Zigbee对Bluetooth没有任何机会。</p>

<div class="tpc_content">近日在一论坛看到大作一篇，题为《ZigBee谁笑到最后》，开篇气势磅礴，颇为专业，中篇渐有曲折，结尾峰回路转，文不对题。<br/>个人认为许多地方不够客观，不太认同其一些说法，这里对我认为不合适的观点做些说明。<br/>(红色/斜体为原文)<br/><font face="Tahoma"><i>A)微处理器： <br/>除了CC2430/CC2431外，其他四家公司都是采用自己的微处理器。只有CC2430/CC2431采用标准的8051处理器。 <br/>该项评分：CC2430/CC2431胜出 </i><br/><br/></font>比较的到底是什么呢？用8051核就胜出？其他公司不说，FREESCALE的处理器难道差么？<br/><br/><font face="Tahoma"><i>因为：8051微处理器诞生30多年，目前在国内最为普及。大学中专，都有广泛的课程，各种参考书，到处都有。开发软件KEIL、 IAR已被大家熟悉，用起来最顺手。 <br/>有言论说8051“老了” 怕不能担当此重任，也有言论说8051会产生数字噪声，影响无线通讯… 以专家的眼光看，这些都是没有科学依据的说法。随着芯片科技的发展，今天的8051早已经脱胎换骨，只是片上系统(SoC)的一小部分，而且在低功耗、高速度、低噪声等方面，有了质的飞跃。CC2430/CC243的8051内核经过特别设计，可以和2.4GHZ的ZigBee无线收发电路完美的配合工作，绝不会因为其8051内核的高速运行而对高频无线通讯有任何影响。 <br/>采用从8051对用户而言好处如下: <br/>1、无需重新学习微处理器结构原理,无需重新熟悉编译/调试工具； <br/>2、对片上系统的I/O，定时器，A/D，PWM，看门狗等等，也无需重新学习； <br/>3、如果你没有单片机的基础，学起来也非常容易，也容易找到人请教、交流； <br/><br/>认同以上观点，但需要说明的是KEIL、IAR都是商业软件，除非使用盗版，不然是要付费用的，而且价格不菲<br/><br/>从技术眼光看，ZigBee技术的核心是软件。如果MCU是8051，则ZigBee是由C51代码组成的一堆软件而已。无论是无线数据传输、路由算法、网络拓扑….都是各种函数的组合、代码组合。任何人熟悉C51编程，就很容易熟悉ZigBee的代码，同时将自己的应用代码和ZigBee结合在一起。 <br/>这对应初次进入无线领域的工程师而言，如果选择自己不熟悉的处理器，在进行开发时，既要面对复杂的ZigBee无线通讯协议，超高频的硬件环境，再加上完全陌生的指令系统，硬件平台，无疑对开发ZigBee是“雪上加霜”。</i><br/><br/><br/></font>据我所知，各大厂家都提供了详尽的API函数库，只需要会C语言就可以开发自己的应用了，完全不需要关心使用的是哪种CPU<br/><br/><font face="Tahoma"><i>B)ZigBee协议栈 <br/>目前TI 提供CC2430/CC2431 ZIGBEE2006协议栈，全套协议栈原来报价10万人民币，目前已经开放免费下载，这是一个巨大的惊人之举。虽然开放下载的协议栈是库文件，但是全功能，包括网状网络拓扑的全功能协议栈，从10万到零，将其他对手远远抛在后面。 <br/>如果需要进行教学研究，无线龙通讯可以提供全部C51源代码的精简版协议栈。 <br/>其他几家情况如下： <br/>FREESCALE BEE KIT 3个月自动失效（需要购买正版1200美元，才能使用）。 <br/>EMBERR ZIGBEE 2006 报价：10，000美元。 <br/>MICROCHIP 免费源代码， 但是只支持PIC和MJ2440芯片。 <br/>该项评分：CC2430胜出。</i><br/><br/></font>补充一下：JENNIC公司的协议栈一直是免费开放下载的，而且其开发环境也是免费的，没有版权问题<br/><br/><font face="Tahoma"><i>C）ZigBee芯片的最后成本 <br/>CC2430、CC2431是全部方案中，唯一一个包括FLASH存储器＋MCU+ZigBee RF全全集成，真正的单芯片解决方案。</i><br/><br/></font>这个目前是事实<br/><br/><font face="Tahoma"><i>JENNIC的“单片机”只有ROM(只读存储器)，芯片内部没有存放用户程序的地方，系统必须要外加一个EEPROM。你的全部程序必须存储在外部的EEPROM中，如果你使用这样的无线单片，最大的问题是不能对你自己开发的代码加密，任何人可以从外部EEPROM轻易中获得你辛辛苦苦开发的代码。 </i><br/><br/></font>可以用软件方法加密，因为MAC地址是唯一的，所以只要加密算法和MAC相关，复制了程序也没办法在MAC地址不同的芯片上运行。<br/><br/><i><font face="Tahoma">FREESCALE 的单芯片是采用两个硅片和SIP技术共同包装，在大量生产情况下，肯定不能和单芯片方案竞争。</font></i>
                <br/><br/>FREESCALE是很有实力的公司，不是么？<br/><br/><font face="Tahoma"><i>在芯片最后成本竞争中，CC2430取胜是必然，因为只有CC2430真真能作到一个芯片解决战斗！芯片价格必然最低！</i><br/><br/></font>关于价格，请大家直接咨询厂家，自行比较 <br/><br/><br/><i><font face="Tahoma">D)开发工具的方便性和开发工具（包括开发软件）的低价格 <br/>CC2430原产开发工具CC2430ZDK报价原来10,000美元，目前下降到2000美元。但是国内无线龙通讯科技公司，已经将全套CC2430/CC2431开发工具（包括USB仿真器，精简版ZigBee协议栈，兼容ZigBee2006，两个ZigBee无线模块，全套开发软件 ）C51RF-3-CS降低到了不到人民币2000元以下(1888元人民币)。</font></i>
                <br/><br/>以JENNIC方案为例子，国内 <a href="http://www.vsdtech.com/" target="_blank"><font face="Tahoma" color="#383e34">www.vsdtech.com</font></a>
                <br/><a href="http://www.mpuhome.cn/" target="_blank"><font face="Tahoma" color="#383e34">www.mpuhome.cn</font></a> 等厂家的JENNIC套件价格仅在1千元左右，最低只有800元的样子</div>
